Light Armor is the skill governing your ability to fight and move in light armor. Each skill point increases your armor rating from Light Armor by 0.4% (1.5% for NPCs). The Light Armor skill tree has a total of 6 perks, requiring a total of 10 perk points to fill.

Can be faster than the enemy, allowing you to run away from a battle or pursue a fleeing enemy.

The lighter weight allows for the carrying of multiple suits of armor, each fine-tuned for specific enemies and situations, without drastically taking up encumbrance.

Fully mastering the Light Armor tree requires two fewer perks over Heavy Armor (10 total points versus 12), allowing for more growth in other skill trees.

Deft Movement has a small chance to negate combat damage, increasing overall defense.

Disadvantages:

Much less protective in the early game. However, later on, with high support skills, both armors are able to reach the protection cap.

Bare fist (unarmed) attacks are less powerful without Fists of Steel, though at present this perk only uses the base value of the armor, not the upgraded value, and this perk can be somewhat replaced with Fortify Unarmed.

Regenerate Health potions and enchantments can heal you while leveling armor skills, potentially allowing you to leave the game unattended. This can also be accomplished with natural health regeneration during brawling sessions with NPCs or fighting very weak enemies like skeevers, though skill gains will be very slow.

Healing while getting bashed is a good way to level the Restoration skill at the same time.

The Block skill can be easily leveled at the same time as Armor skills.

With the Unhindered perk, when you carry more weight than you could without the perk, and you save a game, upon loading from inside the game, you will be over-encumbered (as if you didn't have the perk) until you open your inventory. This typically occurs only after an event, such as your death, removing all of your active effects. If you die and then quickload, you may become affected by this bug until you relaunch the game.

The Unhindered perk is intended to reduce only the weight of light armor that is actually being worn (equipped). However, as of patch version 1.4, Unhindered also reduces the weight of any piece of armor in your inventory that is the same base item as any piece being worn. For example, if you have 10 glass armors in your inventory, equipping one of them will make all of them weightless. This remains true even if the worn armor is enhanced by Smithing, enchanted, and renamed.

Even though Deft Movement claims to only work against melee attacks, it has the same chance to ignore damage from arrows, too. ?
